Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

An embodiment of the present application provides a laser marking method, in an embodiment of the laser marking method of the present application, referring to fig. 1, the method includes:

step S10, when a container to be marked is placed at a designated position, a scale line to be marked on the container and scale content thereof are obtained, and the designated position is determined according to the size of the container and the position of the refractor;

and step S20, adjusting pulse parameters of the laser according to the scale content and container materials of the container, so that the pulse parameters emitted by the laser correspond to laser beams which act on the container through the refractor, and marking of scale marks is completed.

The present embodiment aims at: the method for manufacturing the scale marks on the container is improved, and the complete scale marks are manufactured on the container with the concave-convex structure.

However, the paper pasting scheme and pad printing technology have the defects of large error, acid and alkali corrosion resistance, high temperature resistance, water resistance and scratch resistance, and the applicability range is small because complete scale marks cannot be manufactured on a container (such as a barrel) with a concave-convex structure.

As an example, the laser marking method may be applied to a laser marking system, and referring to fig. 2, fig. 2 is a schematic structural diagram of the laser marking system in an embodiment of the present application, where the laser marking system includes a laser 1, an adjusting component 2, and a refractive mirror 3.

The laser 1 includes a laser emitting unit 12 and a laser generator 11, and a laser beam generated in the laser generator is emitted through the laser emitting unit 12 for laser processing. The laser 1 is arranged on the movable guide rail 5, and the movable guide rail 5 is driven by the stepping motor 8 to drive the laser 1 to horizontally move so as to mark scale marks with a certain length.

The adjusting unit 2 is mounted on the laser emitting portion 12 of the laser 1, and the adjusting unit 2 moves synchronously with the laser 1.

The refractor 3 is installed with the laser 1 through the adjusting component 2, and the refractor 3 is movably installed with the adjusting component 2, so that the refractor 3 can adjust the angle on the adjusting component 2 to determine the route and the position of the laser beam mark.

In this embodiment, the laser marking system further includes a table 6, and the moving rail 5 is mounted on the table 6. When in use, the container is placed on the workbench 6, the refractive mirror 3 on the container is driven by the adjusting component 2 to extend into the container, and the angle of the refractive mirror 3 is adjusted to determine the initial position of the laser beam marked in the container. After the scale marks are marked on the initial positions, the movable guide rail 5 drives the laser 1 and the refractor 3 to horizontally move to the next marking position, and laser processing is carried out on the next marking position through laser beams until the complete scale marks are marked in the container, and the marking is finished.

As an example, the adjusting assembly 2 further includes two extension rods 21 and a ring 22, the ring 22 is sleeved on the outer periphery of the laser emitting portion 12, the ring 22 and the laser emitting portion 12 are fastened through threaded connection, the two extension rods 21 are symmetrically installed on the outer periphery of the ring 22 front and back, and a plane formed by the front and back extension rods 21 is parallel to an operation plane of the workbench 6. The refractor 3 is mounted between the clamping portions 211 on the right side of the extension rod 21.

In this embodiment, an extension rod is added to guide the laser beam into the container, and a refractive mirror is arranged at the terminal end of the extension rod to enable the laser beam to act on the inner wall of the container, so that if the container is too high, the container can be manufactured from the initial position (such as the 0 liter position of the scale mark) of any height by adjusting the angle of the refractive mirror. Not limited to the device configuration, but not to the scale pattern.

As an example, a first screw hole is provided in the side surface of the refractor 3, a second screw hole is provided in the clamping portion 211 at a position corresponding to the first screw hole, and an end portion of the screw penetrates the second screw hole and then is screwed into the first screw hole, so that the refractor 3 is mounted on the extension rod 21. When the angle of the refractor 3 is adjusted, the angle of the refractor 3 is changed by taking out the screw or when the screw is separated from the first screw hole. After the angle of the refractor 3 is determined, the screw is re-screwed with the first screw hole to fix the angle of the refractor 3, and the stability of the refractor 3 is maintained.

As an example, the laser marking system further comprises a terminal device 7, the laser 1 and the movable guide rail 5 are connected with the terminal device, scale marks to be marked in the container are adjusted through the terminal device, and the laser is controlled to manufacture marking contents on the container in equal proportion. The terminal equipment controls the stepping motor 8 to drive the movable guide rail 5 to drive the laser to move for any length (the maximum value of the any length is the length of the movable guide rail, the length of the movable guide rail can be customized according to the needs), and parameters such as pulse number per revolution are adjusted through the terminal equipment, so that the laser can accurately move to the starting point of the next section of scale after manufacturing one section of scale, the accurate manufacturing of each section of scale is realized, and the complete manufacturing of high-precision scale marks on the inner wall of a container with any height is finally realized.

Based on a laser marking system, the laser marking method comprises the following specific steps:

as an example, the containers to be marked include smooth inner wall containers, and also include containers of raised construction, such as barrel containers, measuring cylinders, water tanks, volumetric flasks, and the like.

As an example, the container material to be marked may be a stainless steel material, also PP material or the like.

As one example, the tick content includes tick mark style, tick mark definition, tick mark pitch. The scale mark patterns comprise scale marks of different specifications, such as a volumetric flask of 100ml and 200 ml. The marking definition refers to the marking effect caused by the depth of the scale mark embedded in the inner wall of the container. The scale interval refers to the scale standard of the scale lines with different specifications, for example, if the scale line in a 100ml volumetric flask is selected to be a standard interval every 20ml, the scale line is divided into 5 equal divisions, namely, 5 scale points are arranged on the container.

As an example, a specified position refers to the position of the container on the table when the starting position of the 0 scale of the container coincides with the starting position of the laser beam marked in the container. The designated position is determined according to the attribute of the actual container (such as capacity, barrel diameter and the like) or the marking position requirement of the scale mark, the specification of the scale mark, the position of the refraction mirror and the like.

It will be appreciated that for containers of different diameters of the same volume, the designated location of the tick mark in the large diameter container is less distant from the bottom of the container than the designated location of the tick mark in the small diameter container. Thus, the specified location of the large diameter container on the table may be different from the specified location of the small diameter container on the table.

Because the position of the refractor is not fixed and adjustable, the refractor can be positioned in the marking area in the container with different axial depths, and therefore, the container can be marked with laser only by the position of the refractor, and the appointed position where the container is placed can be determined according to the position of the refractor.

As an example, the specified position of the container is roughly determined according to the axial depth data of the container to be marked, the position and angle information of the refractive mirror and the maximum position interval of the refractive mirror driven by the adjusting component to move. And placing the container to be marked on a workbench to enable the container to be positioned at a designated position.

As an example, the specified position may also be a placement position specified according to specification setting of the container, such as the specified position of the container being uniform within a certain barrel diameter range, or the specified position of the container being uniform within a certain capacity range. Therefore, after the appointed position of the container is initially determined, the marking position of the laser beam in the container can be adjusted according to the extension rod, the movable guide rail and the adjustable guide rail in the refraction mirror and the adjusting assembly, so that the accuracy of the marking position is improved.

As one example, prior to laser marking, a specified position of the container is determined and the laser, the position of the refractor, the angle, etc. are calibrated. Specifically, a sample plate is placed on a workbench, the scale mark to be marked and the content of the scale mark are obtained, if the scale mark is square with the side length of 3 cm, the positions, angles and the like of a laser and a refractor are determined according to the scale content and are correspondingly adjusted, and the scale mark is marked on the basis of adjusted equipment, so that the calibrated scale after sample is obtained on the sample plate. Judging whether the calibrated scale after proofing is consistent with the scale mark to be marked, if so, carrying out scale marking treatment on the container in batches according to the existing equipment configuration; and if the calibration marks are inconsistent, adjusting the calibration parameters such as the positions, angles and the like of the laser and the refractive mirror according to the error between the calibrated marks after the proofing and the marks to be marked until the calibrated marks are completely consistent with the marks to be marked, namely, the calibration of the laser and the refractive mirror is completed.

As an example, the marking content includes a scale pattern of scale marks, a marking definition, and a scale interval, pulse parameters of the laser are adjusted according to the marking definition requirement and the material of the container to be marked, and the laser intensity of the laser beam emitted by the laser is determined according to the pulse parameters. It will be appreciated that the greater the pulse parameter the greater the depth of marking of the laser beam as it acts on the container, the darker the colour of the graduation mark, and more discernable. The pulse parameters are determined according to the actual marking requirements and are not particularly limited herein.

As an example, the color of the graduation marks is not only related to the pulse parameters but also to the material of the container to be marked. For example, if the pulse parameters of the laser are 20, the pulse parameters are respectively applied to the first container made of PP plastic and the second container made of white PP plastic, and the first container and the second container are made of different materials, the scale mark marked on the first container by the laser can hardly see the scale color, and the scale mark marked on the second container by the laser has the very black scale color, so that the contrast ratio is large and the definition is better. Therefore, the laser beam pulse parameters of the laser are adjusted according to the container material of the container, and the adjusted laser beam is used for marking the container.

As an example, the laser marking system further comprises a terminal device, wherein the terminal device is connected with the laser, and the pulse parameters are determined through scale content received or input in the terminal device. The terminal equipment controls the laser to emit laser beams corresponding to the pulse parameters so as to mark scale marks on the container.

As an example, the scale content also comprises scale data of each scale, and the scale parameters of the scale lines are adjusted by the terminal equipment so as to adapt to the scale data of 1 in the scale areas of different containers: 1, and accurately manufacturing scale marks. The scale marks are the material of the container, and have the excellent properties of the container material (such as stainless steel material, pp material and the like) such as water resistance, strong acid and alkali corrosion resistance and high temperature resistance. Therefore, the scale mark which is made by carving deep into the material by laser has the advantages of water resistance, strong acid and alkali corrosion resistance and high temperature resistance. In general, the cutter scrapes the scale mark without losing color, unless the material is scraped and damaged, the service life of the scale mark is dependent on the service life of the container, and the cutter is not limited to the manufacturing process of the scale mark, so that the service life of the scale mark is obviously prolonged.

As an example, the step of adjusting the pulse parameters of the laser according to the scale content and the container material of the container, so that the pulse parameters emitted by the laser correspond to the laser beam and act on the container through the refractor, so as to complete the marking of the scale mark includes:

Step S21, adjusting the position or angle of the refractor so that the laser beam emitted by the laser at the initial position passes through the refractor and then acts on a preset marking starting point;

step S22, adjusting laser beam pulse parameters of the laser according to container materials of the container, and marking the marking starting point by using the adjusted laser beam to form a starting scale;

and S23, determining other scale positions of the laser beam on the container according to the scale content, and marking the other scale positions with scales so that all the scale lines are marked on the container.

As an example, the refractive mirror is connected with the laser through the adjusting component, and the laser and the refractive mirror are of a combined integrated structure, namely, the refractive mirror is driven to synchronously move when the laser moves, so that the stability of the laser beam emitted by the laser acting on the refractive mirror process is maintained.

As an example, the adjusting assembly comprises two extension rods, and a refractive mirror is arranged between clamping parts on the right sides of the extension rods, and the position of the refractive mirror on the extension rods can be adjusted. The position of the refractor can be changed by the extension rod, and the laser beam passes through the refractor and then acts on the position in the container. The laser beam is guided into the container by adding an extension rod, the laser beam can act on the inner wall of the container by arranging a refraction mirror at the terminal end of the extension rod, and if the container is oversized or overhigh, the manufacture is realized from the marking starting point of the container with any height by adjusting the position of the refraction mirror on the extension rod and the angle of the refraction mirror.

As an example, the tick mark start point refers to the tick mark start position. It should be noted that, the initial position of the graduation mark represents a capacity value not necessarily equal to 0, and it is understood that, for a 100ml container, if it is necessary to mark a graduation mark of 100ml, the starting point of the graduation mark may be a position of 0ml, a position of 20ml, or a position of 50 ml. Therefore, according to the pattern and the data of the scale mark, the determined scale mark starting point refers to the starting position of the scale mark.

As an example, according to a preset marking starting point in the container, the position of the refraction mirror on the extension rod and the angle of the refraction mirror are adjusted, so that the laser beam emitted by the laser device acts on the marking starting point after passing through the refraction mirror, and accurate positioning of the scale mark is realized. The position of the container can be adjusted, so that laser beams emitted by the laser device act on the marking starting point after passing through the refractive mirror, and the accurate positioning of the scale marks is realized.

And the terminal equipment controls the laser to emit laser beams, the laser beams act on the marking starting point of the container after passing through the refractor, and the marking starting point is marked or processed under the action of laser to form a starting scale. After the initial scale is marked, other scales and the scale data in the scale marks are marked sequentially according to the scale content, and the scale marks are manufactured at other positions of the other scales on the container, which are needed to be marked, so that the equal-proportion accurate manufacturing of the scale marks is completed.

As an example, before the step of adjusting the position or angle of the refractive mirror so that the laser beam emitted by the laser in the initial position passes through the refractive mirror and then acts on the preset marking starting point, the method further includes:

step S24, determining the marking start point according to the scale mark and the preset marking area on the container.

As an example, the containers to be marked are provided with preset marking areas before marking, and the marking areas are determined according to the display requirements of the scale marks, such as the forward inner wall of the container and the side wall of the container. The marking area can also be determined according to the size of the scale mark manufactured on the container. Therefore, according to the scale mark proportion and the marking area to be manufactured on the container, the marking starting point is determined, so that the whole scale mark is positioned in the marking area.

As an example, the scale content includes a scale definition, the step of adjusting a laser beam pulse parameter of the laser according to a container material of the container, and marking the scale starting point by using the adjusted laser beam to form a starting scale includes:

step S221, adjusting pulse parameters of the laser according to the marking definition and the container material;

Step S222, marking the inner wall of the container based on the laser beam emitted by the laser device and corresponding to the pulse parameter, so as to form an initial scale.

As an example, the marking definition, i.e. the intensity of the laser beam acting within the container, is included in the marking content to make the manufactured graduation mark identifiable.

The terminal equipment determines the pulse parameters of the laser according to the information of the marking depth, and controls the laser energy of the laser beam emitted by the laser according to the pulse parameters so as to mark the inner wall of the container by the laser beam corresponding to the pulse parameters, thereby forming a certain identification initial scale.

The definition of all scales in the scale marks can be embodied by the scale mark depth, and the scale mark depth can be the same or different. When the marking depths are different, the scale with larger marking depth can be selected according to the display requirement of the scale lines. For example, in a scale mark of 100ml, if 10-division scale of 10ml is divided into 10-division scales for each 10ml, each scale represents 1ml. At this time, the marking depth of each scale corresponding to 10ml can be selected to be larger than the marking depth of each scale corresponding to 1ml, so as to embody different scale mark effects or patterns and realize the flexibility of scale mark manufacturing.

As an example, the calibration content further includes calibration coordinates, and the step of determining other calibration positions when the laser beam acts on the container according to the calibration content, and performing calibration marking on the other calibration positions so that all the calibration lines are marked on the container includes:

step S231, obtaining scale coordinates of other scale positions in the scale mark;

and step S232, based on the scale coordinates, performing scale marking on the other scale positions by controlling the action positions of the laser beams of the laser on the container so as to make all the scale marks marked on the container.

As an example, when the scale line and the scale content are acquired, the coordinate and size information of each scale can be obtained through the display software of the terminal. In the marking process, the angle of the laser internal vibrating mirror is controlled by acquiring the coordinates of the scale, so that the laser beam acts on the container to form the scale, and the marking of the scale mark is completed.

As an example, the scale content also includes scale spacing, which refers to the distance between each scale in a scale line. Since the graduation marks represent parameters such as the capacity or the volume of the container, the graduation marks are the same as the axial direction of the container and have a certain length. After the initial scale is manufactured, the laser is required to mark the next scale, so that the complete scale mark can be manufactured.

Therefore, the angle of the laser internal vibrating mirror is adjusted through the scale interval, so that laser beams act on different positions of the refracting mirror after passing through the vibrating mirror, under the condition that the position and the angle of the refracting mirror are unchanged, the position of the laser beams acting on the container after passing through the refracting mirror is changed, namely, the position of the laser beams acting on the next scale on the container is changed, so that the marking of the next scale is completed, interval scales are formed, and until the scales on the scale lines are marked on the container completely, at least one interval scale is formed. And the complete marking process of the scale marks is realized by the marking of the initial scale and at least one interval scale.

The distance between the adjacent initial graduations and the interval graduations or the distance between the adjacent interval graduations is equal to the marking distance.

As an example, when the scale in the scale line is in a stripe shape, the step of obtaining the scale coordinates of other scale positions in the scale line includes:

step S2311, acquiring coordinate information of all scale points forming a current scale line;

and S2312, adjusting the angle of the laser internal vibrating mirror based on the coordinate information so that the laser beam passes through the vibrating mirror and the refracting mirror to form the scale marks on the container.

As an example, each scale having a length in the scale line is formed by a plurality of scale points, and when the scale line and the scale content are acquired, the coordinates of each scale point can be obtained through the display software of the terminal, so as to obtain the scale coordinates of other scale positions in the scale line. In the marking process, the coordinates of the scale points are obtained, and the angle of the vibrating mirror in the laser is controlled, so that laser beams act on the container to form the scale points. And forming scales through continuous scale points, thereby completing the marking of the scale lines.

As an example, the two-dimensional galvanometer and the three-dimensional galvanometer are used as the galvanometer in the laser, the working principle is described by taking the two-dimensional galvanometer as an example, specifically, the two-dimensional galvanometer is 2 refractors, after the laser beam is emitted, the computer controls the reflection angle of the refractors according to the scale content, and the two refractors can scan along X, Y axes respectively, so as to achieve the deflection of the laser beam, and the laser focusing point with certain power density moves on the marking material according to the required requirement, so that permanent marks are left on the surface of the material. Since the refraction mirror is arranged at the laser emission port, the direction of the laser beam deflected by the X, Y axis can be changed again after reaching the refraction mirror, and the laser beam acts on the surface of the container, and when the laser is calibrated, the reflection angle of the refraction mirror is adjusted, so that the carved content of the laser beam passing through the refraction mirror on the surface of the material is consistent with the scale mark to be marked.

step A1, carrying out sectional processing on the scale marks based on a preset etching distance to obtain at least one section of scale area;

step A2, marking each section of the scale area, and executing the step of adjusting the position or angle of the refractor according to the mark so that the laser beam emitted by the laser at the initial position acts on a preset marking starting point after passing through the refractor;

a3, if the current scale area marking process is finished, controlling a stepping motor to drive the laser to move according to the preset marking distance so that a laser beam of the laser acts on a marking starting point of the next scale area, wherein the laser is arranged on a moving guide rail driven by the stepping motor;

and A4, carrying out scale marking on the next scale area through the laser beam until all the scale areas are marked.

As an example, the preset inscription distance refers to an inscription distance or an area distance set at the time of segment inscription. Dividing the scale mark into at least one section of scale area according to the preset etching distance, carrying out etching treatment on each section of scale area, and executing the step of adjusting the position or angle of the refractive mirror according to the preset etching distance so that the laser beam emitted by the laser at the initial position acts on the preset etching starting point after passing through the refractive mirror. Namely, each section of scale area is provided with an initial scale and an interval scale, and the complete manufacture of the scale mark in the current scale area is realized through the adjustment of the laser inner vibrating mirror.

As an example, the laser is mounted on a moving rail driven by a stepper motor, and the terminal device controls the laser to move through the stepper motor to mark scales at other positions.

As an example, the terminal device determines the distance moved by the laser after each section of scale area has been made according to the preset scribing distance. When the scale mark is manufactured, the terminal equipment controls the stepping motor according to the preset etching distance so that the laser on the stepping motor moves to the position of the next section of scale area, the initial acting position of the laser beam is overlapped with the initial scale of the next section of scale area, then the laser beam emitted by the laser marks all scales in the next section of scale area after passing through the refractor, until all scales on the scale mark are marked in the container, and then the marking is finished, so that a complete scale mark is formed.

In the embodiment, after the laser is controlled by the stepping motor to finish the graduation of one section of graduation area by the laser marking machine, the laser is precisely moved to the starting point of the next section of graduation area, and finally, precise graduation line manufacturing is performed on the inner wall of the container with any height.

As an example, if the graduation line is a complete and continuous straight line, the terminal device controls the laser to move smoothly through the stepping motor, and the laser continuously emits a laser beam during the movement process so as to make the graduation line continuous. Therefore, the manufacturing requirements of different types of scale marks can be met by controlling the laser beam of the laser, the work of the stepping motor and the position of the refractor, and the high-precision characteristic of the laser is utilized when the laser marks the scale content on the inner wall of the container, so that the precision and the application range of the scale mark manufacturing are improved.

For example, if the scale mark is larger than the preset scribing distance of the laser, when the laser scribes the scribing content within the preset scribing distance (i.e. the immediate area), the moving guide rail will drive the laser to automatically move the preset scribing distance to manufacture the next scale mark. For example, the preset scribing distance of the laser is 3 cm long, the laser is used for scribing the graduation marks within 3 cm long, the movable guide rail can automatically move for 3 cm, and the laser continues to scribe the graduation marks within the next 3 cm long until the graduation marks are completely scribed.

It should be noted that, before laser marking, the moving process of the laser and related equipment need to be calibrated to improve the accuracy of the scale mark marking. Specifically, a rectangular manuscript (such as 30 cm) with equal length with the scales is manufactured, the movable guide rail is triggered to move after the laser finishes manufacturing the engraved content within the preset engraved distance, the size of the scales after the proofing is measured, and the pulse number per revolution of the movable guide rail is calibrated until the obtained scales are completely consistent with the scale marks to be engraved, namely the movable guide rail is calibrated. It will be appreciated that the preset scribing distance of the laser may be 1 mm, i.e. 1 mm of content is scribed, the moving rail is moved 1 mm, the preset distance is 3 cm, i.e. 3 cm of content is scribed by the laser, and the moving rail is moved 3 cm.

The preset distance may be a default software dividing mode, or may be set according to the situation, for example, the preset distance is 15 mm, which is not limited herein.

Compared with the prior art that a complete scale mark cannot be manufactured on a container with a convex structure, the laser marking method is applied to a laser marking system, the laser marking system comprises a laser and a refractive mirror, and the method comprises the following steps: when a container to be marked is placed at a specified position, a scale line to be marked on the container and scale content thereof are obtained, and the specified position is determined according to the size of the container and the position of the refractor; and adjusting pulse parameters of the laser according to the scale content and container materials of the container, so that the pulse parameters emitted by the laser correspond to laser beams which act on the container through the refractor, and marking of scale marks is completed. Namely, the scale marks are marked on the container through a laser processing technology, the marking position of the laser beam on the container is changed through the refractor, the purpose of manufacturing the scale marks on the inner wall of the container is achieved, as the scale marks are manufactured on the inner wall of the container, the concave and convex of the outer structure are not affected, the laser marking device is applicable to the container with the concave and convex structure, and the application range of laser marking is enlarged.
